Field Controls SWG-4HD Heavy Duty Power Venter 4 in 170,000 BTU/HR 46275400

The Field Controls SWG-4HD is a heavy-duty sidewall power venter (draft inducer) for gas and oil-fired furnaces, boilers and water heaters. It combines the motor, blower and vent hood in one unit. It mounts on the outside of the building and pulls combustion gases from the appliance through the outside wall, keeping the vent pipe under 100 percent negative pressure.

Key Features:

• Rated for 170,000 BTU/HR input, with a 1.10 GPH oil rating
• 4 in inlet size
• 115 V, 60 Hz, 1.7 A, 138 W motor running at 3000 RPM
• Thermal protection built in
• Standard galvanized vent pipe can be used in place of stainless steel
• Vent pipe joints do not need to be sealed
• Allows longer vent lengths than positive-pressure, direct-vent systems

The venter must be sized to match the appliance's input firing rate, which is usually published in the appliance manufacturer's installation manual. It must be installed with a CK control kit for proper listing and safe, efficient venting. Field Controls part number 46275400.
